In Situ Curing‐Enabled 3D Printing of Continuous Fiber‐Reinforced Thermosetting Composites

open access: yesJournal of Polymer Science, EarlyView.
In situ curing‐enabled the 3D printing of continuous fiber/thermoset composites, which were reviewed. Particularly, four types of in situ curing, were discussed, including Radiation‐induced curing, photothermal curing, electrothermal curing, and frontal polymerization. AI‐integrated printing was also analyzed.

Formation Control With Obstacle Avoidance of Underwater Swarms Based on Relative Visual Feedback

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Underwater multi‐robot and swarm systems require advanced methodologies for controlling collective behavior. Conventional single‐robot techniques, such as tethering, sonar imaging, and acoustic localization, are not scalable or effective for swarm applications.

Invisible near‐infrared thermo‐stimulated luminescence from carbon dots enabled by stepwise energy transfer for concealed information encryption

open access: yesResponsive Materials, EarlyView.
A fully metal‐free near‐infrared (NIR) thermo‐stimulated luminescent system is developed by embedding carbon dots into a carbon nitride matrix and integrating multistage Förster resonance energy transfer. The system exhibits long‐term charge retention, rewritable optical memory, and highly concealed NIR readout, promising for secure data encryption and

Color Vision Defects in Early Diabetic Retinopathy

JAMA Ophthalmology, 1986
Four color vision tests were used to assess color vision in 51 insulin-dependent diabetic patients and 41 normal controls. Right and left eyes of diabetic patients, selected because they had minimal retinopathy, had significantly more color vision defects than controls on Lanthony desaturated D-15, Farnsworth-Munsell 100-Hue, and chromagraph tests. The

Acquired Color Vision Defects in Retrobulbar Neuritis

American Journal of Ophthalmology, 1978
We used the Farnsworth-Munsell 100 Hue Test to study the incidence of acquired color vision defects in 16 patients with unilateral and and seven patients with bilateral retrobulbar optic neuritis whose visual acuity had recovered to 6/12 (20/40) or better. We recorded the visual-evoked response to a pattern stimulus on the same day.

Color-Vision Defects in American School Children

JAMA - Journal of the American Medical Association, 1964
A study of color-vision using Ishihara plates and the pseudoisochromatic plates designed by Hardy, Rand, and Rittler (HRR) was made of 10,341 students in all grades in an American school district. The tests were compared and the Ishihara plates were found more accurate for detecting defects, and the HRR more apt to give problems in interpreting results
